Solution: In hibernate you should always use actual java class name and its property name when execute query against database in place of data base table and column name. In our case exception thrown because we were using actual table name below:

List<Address> address3 = session.createQuery("from address").list();

Corrected table name to class name below:

List<Address> address3 = session.createQuery("from Address").list();
